Impact of Optical Coherence Tomography-Based Post-PCI Physiology Assessment to Predict Clinical Outcomes: An ILUMIEN-IV Substudy.

Background: A novel optical coherence tomography (OCT)-based physiology assessment technique, virtual flow reserve (VFR), has been demonstrated to perform as a reliable surrogate for invasive physiology.

Objectives: The authors sought to examine the performance of post-percutaneous coronary intervention (PCI) VFR as a predictor of 2-year clinical outcomes independent from the OCT-based minimal stent area (MSA).

Methods: The ILUMIEN IV (Optical Coherence Tomography [OCT] Guided Coronary Stent Implantation Compared With Angiography: A Multicenter Randomized Trial in PCI) trial prospectively recruited 2,487 patients with diabetes or high-risk coronary lesions randomizing to OCT- vs angiography-guided drug-eluting stent implantation.

Impact of SGLT2-inhibitors on acute kidney injury in diabetic patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI).

Background: Acute kidney injury (AKI) following transcatheter aortic valve implantation (TAVI) is associated with significantly worse outcomes, leading to increased short- and long-term mortality. We sought to evaluate the impact of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on the risk of AKI in patients with type 2 diabetes mellitus (T2DM) and severe aortic stenosis (AS) undergoing TAVI.

Methods: Multicenter international registry of consecutive T2DM patients with severe AS undergoing TAVI between 2021 and 2024.

Artificial intelligence for the analysis of intracoronary optical coherence tomography images: a systematic review.

Intracoronary optical coherence tomography (OCT) is a valuable tool for, among others, periprocedural guidance of percutaneous coronary revascularization and the assessment of stent failure. However, manual OCT image interpretation is challenging and time-consuming, which limits widespread clinical adoption. Automated analysis of OCT frames using artificial intelligence (AI) offers a potential solution.

SGLT2-inhibitors in diabetic patients with severe aortic stenosis and cardiac damage undergoing transcatheter aortic valve implantation (TAVI).

Background: A substantial number of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) experience adverse events after TAVI, with health care expenditure. We aimed to investigate cardiac remodeling and long-term outcomes in diabetic patients with severe AS, left ventricular ejection fraction (LVEF) < 50%, and extra-valvular cardiac damage (EVCD) undergoing TAVI treated with sodium-glucose cotransporter-2 inhibitors (SGLT2i) versus other glucose-lowering strategies (no-SGLT2i users).

Methods: Multicenter international registry of consecutive diabetic patients with severe AS, LVEF < 50%, and EVCD undergoing TAVI.

Association Between Coronary Artery Spasm and Atherosclerotic Disease.

In at least one-half of the patients with angina or ischemia and nonobstructive coronary arteries undergoing coronary function testing, coronary artery spasm (CAS) is detected. CAS is associated with an adverse prognosis regarding recurrent complaints and ischemic events. Current treatment options are mainly focused on the complaints, not on the underlying pathophysiological process.

A novel balloon-expandable transcatheter aortic valve bioprosthesis: Myval and Myval Octacor.

Introduction: Over the past two decades, transcatheter aortic valve replacement (TAVR) has expanded its application across all surgical risk levels, including low-risk patients, where, due to longer life expectancy, reducing common pitfalls of TAVR is essential. To address these needs, many technological advancements have been developed. Myval and the new generation Myval Octacor (Meril Life Sciences Pvt.

Drug-coated balloon versus drug-eluting stent for treating de novo large vessel coronary artery disease: a systematic review and meta-analysis of 13 studies involving 2888 patients.

Introduction: Drug-coated balloon (DCB) is an established treatment option for in-stent restenosis and small vessel, de novo, coronary artery disease (CAD). Although the use of this tool is increasing in everyday practice, data regarding performance in the treatment of de novo, large vessel CAD (LV-CAD) is still lacking. A systematic review and meta-analysis were conducted to evaluate the efficacy and safety of DCB versus drug-eluting stent (DES) in this setting.

Percutaneous Coronary Intervention before or after Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis Involving 1531 Patients.

The optimal timing to perform percutaneous coronary interventions (PCIs) in patients undergoing transcatheter aortic valve replacement (TAVR) is not well established. In this meta-analysis, we aimed to compare the outcomes of patients undergoing PCI before versus after TAVR. A comprehensive literature search was performed including Medline, Embase, and Cochrane electronic databases up to 5 April 2024 for studies that compared PCI before and after TAVR reporting at least one clinical outcome of interest (PROSPERO ID: CRD42023470417).

Comparing two-year outcomes of balloon-expandable Myval and self-expanding Evolut R in severe aortic valve stenosis.

Background: The new balloon-expandable (BE) Myval transcatheter heart valves (THV) has shown promising early results with low paravalvular leak (PVL) and permanent pacemaker implantation (PPI) rates. Limited data are available regarding its long-term performance. We aimed to compare the 2-year clinical and echocardiographic outcomes of transcatheter aortic valve replacement (TAVR) using the self-expanding (SE) Evolut R and the BE Myval THVs.

Percutaneous Treatment of Left Main Disease: A Review of Current Status.

Percutaneous treatment of the left main coronary artery is one of the most challenging scenarios in interventional cardiology, due to the large portion of myocardium at risk the technical complexity of treating a complex bifurcation with large branches. Our aim is to provide un updated overview of the current indications for percutaneous treatment of the left main, the different techniques and the rationale underlying the choice for provisional versus upfront two-stent strategies, intravascular imaging and physiology guidance in the management of left main disease, and the role of mechanical support devices in complex high-risk PCI.

Determinants and long-term outcomes of largely uncovered struts in thin-struts drug-eluting stents assessed by optical coherence tomography.

Background: Uncovered struts are a determinant of stent failure. The impact of plaque composition and procedural factors on the occurrence, evolution, and outcomes of uncovered struts in a high-risk setting has not been investigated.

Objective: To investigate the determinants and long-term clinical impact of largely uncovered struts (LUS) in thin-struts drug-eluting stents (DES) implanted in complex lesions by intracoronary optical coherence tomography (OCT).

The association between sexual orientation and eating disorders-related eating behaviours in adolescents: A systematic review and meta-analysis.

Background: Sexual orientation is usually developed during the adolescence, which coincides with the eating disorders peak onset. This paper aims to explore existing literature to identify whether there is an association between sexual orientation and eating disorder-related eating behaviours (EDrEBs) in this age-group.

Methods: This review was based on the PRISMA guidelines, covering the published articles between 1990 and 2021.

Features of atherosclerosis in patients with angina and no obstructive coronary artery disease.

Background: An association between atherosclerosis and coronary vasospasm has previously been suggested. However, to date, no conclusive data on the whole spectrum of these disorders have been published.

Aims: This study aimed to define specific morphological features of atherosclerosis in patients with angina and no obstructive coronary artery disease (ANOCA) due to coronary vasospasm.
